I had lap band surgery on july 6th, 2009.  I am 3 weeks post op and have lost a total of 12 lbs.  Hoping that I would have lost more, but after the second week have been having trouble.  My recovery was quick.  I feel great, but am frustrated that i gave not lost more weight.  I have not had a filling yet.  My doctor is going on vacation for a month so I have to weight till sept. to have my first filling.  I have always been over weight but in the last 10 years have been on a lot of weight.  I had a friend who had the surgery 8 years ago and she looks amazing.  My insurance paid for the surgery so I am very lucky.  Looking for anyone's advice on how to stop the cravings and hunger.
